Description

fan mount

technical field

The invention relates to a fan fixing device, in more detail, relates to a fan fixing device which can realize hot plugging, can save the placement space, and can improve the heat dissipation efficiency of the fan.

Background technique

With the increasing amount of data processing today, users have higher and higher requirements for real-time processing, and multi-processor computers such as servers are more and more widely used. Due to the use of multiple processors, more servers will be generated during operation. If the server with multiple processors has poor heat dissipation, it will also affect the efficiency and stability of its operation, and even cause the server to fail to operate normally. Therefore, manufacturers of various computer equipments usually install a plurality of fans in the chassis to enhance the air flow inside the chassis, so that the heat generated by the computer equipment during operation can be dissipated in time.

However, installing multiple fans in the chassis requires a lot of space to place the fans, especially when there are redundant fans, more space is required. Facing the multi-functional requirements of electronic devices such as servers and the increase in the density of electronic components in them , the rational use of space is particularly important. At present, the fan sizes commonly used in the industry mainly include 120mm×120mm×38mm and 120mm×120mm×25mm, and fans of this size will inevitably occupy a large space in the server.

As shown in Figure 1, it is a structural schematic diagram of the existing heat dissipation system. As shown in the figure, the heat dissipation system 1 is equipped with a fan frame 10, which is used to connect two fans 11 and 12 in series to form a fan frame. The redundant fan heat dissipation system can realize the hot-swappable function of the two fans 11 and 12. However, there is such a problem in adopting this cooling system, that is, no matter whether the fan 11 is working or the fan 12 is working, the airflow generated by the fan is always blocked by the blade of the other fan (airflow direction C as shown in the figure), to reduce cooling efficiency. At the same time, due to the limitation of the specification of the fan, it is not easy to increase the additional fan accommodation space.

However, some people in the industry have proposed a solution, which is to use the original 120mm×120mm×38mm fan space to accommodate four 60mm×60mm×38mm fans. At this time, two of them can be stacked up and down. The problem of not needing to increase the fan accommodation space is solved.

However, since the four 60mm×60mm×38mm size fans all adopt the structure of the previous fan frame 10, that is, a single fan frame accommodates a single fan, so once the fan located on the lower floor fails, because the backup unit is located on the upper layer If the fan circuit breaker blocks the passage of the power supply, the hot-swappable function of the fan located at the lower layer cannot be realized.
